What is CONDUCTOR MATERIAL

Electrical Conductor

Theconductoris a material which contains movableelectric charges. In the metallicconductorslike the copper and the aluminum, the movablechargedparticles are theelectrons. Theelectronsare the negativechargecarriers. The positivechargesare also being mobile in the form of the atoms bound in the crystal lattice which have the missingelectrons. These are known asholes. These are in the form of the mobile ions, like in the electrolyte of the battery, or such as the mobile protons in the protonconductorsemployed in the fuel cells. Theconductorword can also be used at the place of wire because these are also used for the flow ofelectrons.

The all theconductive materialsdon’t have the same level of theconductivity. Similarly not all the insulators are equally resistant to theelectronmotion.The electrical conductivityis same to the transparency of the certain materials to the light. Theconductor materialsthat easily conduct the light are called "transparent," while those that don't are called opaque. While all the transparentconductor materialsare not equallyconductiveto the light. Silver is the bestconductorso that there is easier passage of theelectronscompare to any otherconductor material.The dirty water and the concrete are alsoelectric conductors, but these materials are comparatively less conductive than any other metal. Some of theelectrical materialsexperience changes in their electrical properties under the different conditions. Glass, for instance, is a very good insulator at room temperature, but becomes a conductor when heated to a very high temperature. Gases such as air, normally insulating materials, also become conductive if heated to very high temperatures. Most metals become poorer conductors when heated, and better conductors when cooled. In the normal motion of the freeelectronsin theelectrical conductoris random, there is no particular direction or the speed. Theelectronscan be influenced to move in a particular manner through theconductive material. This uniform motion of theelectronsis the electricity, or the electric current.

All theelectrical conductorscontain theelectric charges. These will move when an electric potential difference which measured in volts is applied across the separate points on the material. This flow of thechargeis the current which measured in amperes. This is known as is electric current. In most of the materials, the direct electric current is proportional to the applied voltage according to the Ohm's law but provided that the temperature remains constant and the material also remains in the same shape and state. Most of theconductorsare metallic.
